Question Is anyone using the Zotac 5070 Twin Edge ?

[_D_D]

If so, what are full load (250W) temperature deltas like with 2 fans?

Thank you for your reply.

Coolers are different between 5060Ti and 5070 plus there's a TGP difference of 180W vs 250W, about 40%. Perhaps @Healer21 would comment? I would be grateful if temperature delta's of GPU and mem are known at full power vs idle and fan speed would be nice too.

Room temp is a cool 29C here with 35C on the mainboard idle without the effect of 200W+ plus of GPU power, so concerned.

There is no ideal idle temp. Since idle temp vastly differs by ambient temp, cooling solution, fan RPM, fan size and fan amount. (Dust too.)

Hence why, there are no idle temp charts in component reviews. Only under load ones.
E.g RTX 5070 review temp chart: https://www.techpowerup.com/review/nvidia-geforce-rtx-5070-founders-edition/41.html

Note: You will never get lower temps than ambient temps. Since PCs are cooled by ambient air.
Also, idle temps doesn't matter because even the smallest cooler can keep CPU/GPU near ambient temps. What matters, is under load temps, since there you can see the effectiveness of your cooling solution (usually balance between noise and temperature target).

E.g in my Skylake build (full specs with pics in my sig), idle temps currently are:
* 27.2C - ambient
* 30C - CPU (i5-6600K)
* 42.7C - GPU (GTX 1660 Ti)
* 41C - MoBo chipset (Z170)
* 49C - OS drive (970 Evo Plus 2TB)
* 35C - OS backup drive (960 Evo 500GB)
* 33C - data drive (870 Evo 2TB)
* 36C - data backup drive (MX500 1TB)

But these values of mine will tell you 0, since you do not have the same ambient, components and airflow setup as i have.


In the review, RTX 5070 temp delta is up to 35C. Not that it would matter, since GPU would remain under 80C under load.
Now, if you're building mini-ITX system with few or no case fans, GPU (and CPU too) can be cooked into thermal throttle.

Here's an example of what I was hoping for.

Take this graph.

Doesn't start from idle but good enough to extrapolate the FE from 85W to 275W for a temperature delta of 39C. From that we can calculate thermal properties to be around 0.2C/W. At 250W we would expect 50C temperature rise plus local ambient temperature (the temperature in the case being delivered to the GPU fans, not room temperature). So for someone with a local ambient of 20C GPU temperature would be 70C at 250W while someone else with a local ambient of 40C would be at 90C. These are just ball park figures and don't take into account such as thermal latency. The rise in local ambient temperature due to a hot GPU will also rise and so the GPU temperature. It's good enough for me. Also that particular graph indicates constant fan speed but likely not 100%. Still it can suffice as an example.

When I searched for the Zotac 5070 twin edge it came back quoting "Tank-like build quality, great performance and low temperatures." and indeed it was on their 5070 product page. A little dig however showed the quote was from a 5080 review, not the 5070.

At this time I'm thinking I'm going to have to get a 3 fan model for peace of mind which is USD100+ more (USD750+) 🙁

I have the zotac twin edge oc. pretty chill card.
Idle temps stays at 44c to 49c since the fans only starts spinning when it hits 50c mark.
while playing games at 100% useage the temps stays between 63 and 65.
I tried undervolting and the temps dont go above 59c at 100% load.
While overclocking temps reach 72c.
I was going to get the 3 fan model luckily one was being tested in the shop from where i bought the GPU.
The card looked way too big and had a sag bracket attached. I did not like the look of it.
Also for some reason it was reaching 72c at full load gaming it was an open case benchmarking.
I cant be 100% sure about the temps on the solid card since i only saw the test once.
You dont have to worry about temps in twin edge oc if u have a case with good airflow.
twin edge 5070 blows air back of the card so if u have an ir cooler which faces that direction cpu can get a bit warm like plus 2c to 5c.
If having liquid cooler then ur chill as a freezer. Also it looks pretty neat.
Happy Gaming

Doesn't start from idle

Does start at idle. Since even on idle, GPUs consume power and produce heat. Also, this much is said in the review;

For this test, we first let the card sit idle to reach thermal equilibrium.

Also, page 41 has the chart, where it shows GPUs to idle between 37C and 40C. Which includes ambient temp.

At 250W we would expect 50C temperature rise plus local ambient temperature

It doesn't work like that.

Chart you linked, shows most RTX 5070 versions at 250W, between 55C and 63C, while FE is 76C. This is GPU temp where ambient temp is included as well (since GPUs are cooled by ambient air).

So for someone with a local ambient of 20C GPU temperature would be 70C at 250W while someone else with a local ambient of 40C would be at 90C.

If that would be true, then test setup ambient temp would've been 0C (for GPU to reach 50C at 250W). But no-one is going to test GPUs in 0C ambient.

Thanks @Healer21 Nice that it works well at a better price than others. I chickened out with 2 fan models and got the Palit gamerpro non OC instead. Some things to learn here such as change in VBIOS again, non-smart 4 phase VRM controller :{ seems GPU is quite leaky too. Unlike the OC version with a 300W TGP setting this one fixed at 250W or up to 30% below IIRC. Missed out on free DOOM. Temps are okay though.

The chart starts at 85W using a custom load, not idle.

Ambient temp is not local ambient, well nearly never.

If that would be true, then test setup ambient temp would've been 0C (for GPU to reach 50C at 250W). But no-one is going to test GPUs in 0C ambient.

50C is the temperature from the power dissipation of the device at 200W, not the junction temperature. While the math is a little over simplistic it's good enough for my use.
